To all whom 'it' may concern:

Be itulrnown that ll., @Eamonn lvl'. liircrij i nnenne, a citizen olz the United States,and resident of Pittsfield, in the county oft Berlishire and State of li/lassachusetts', have in vented certain new andl useful improvements in ldilater-Cooling1 Devices, oi which the following is'a sjecication.

lvl'y invention relates in general to a water cooling= device' and particularly relates to such a device forming part ci a system for sterilizing drinking water and other potable liquids. 7lhis application forms a di'- vision oic my co-pending application for 'Water systems, Serial No. 715017', tiled August le,

@ne of the objects of the invention is to provide an economical means for rapidly cooling,l liquids for drinking and otherA purposes, which liquids have been previously subjected to a boiling, sterilizingg1 or similar heating' treatment.

Another object is toprovide a means 'or subjecting the liquid to a two stage cooling operation and to provide means ifor regulating the admission of the fluid from one cooling device to the other, operatively dependent upon the amount of liquid in the device.

Still another object ol the invention is to provide a cooling means, which may be continuously open to a constant source ci liquid supply and which will maintain but a limited amount o1"- the liquid under the influence of the cooling mediinna A.

Various other objects and advantages of the invention will be in part obvious from an inspection oi the accompanying drawings and in part will be more fully set forth in the following description of one form oi' mechanism embodying the invention, and the invention further consists in certain new and novel features of construction and combination ofparts hereinafter set forth and claimed, f

Referring to the accompanying drawings:

Fig. 2 is a fragmented horizontal sectional View of the ice tank on the line wof Fig. 1 with some of the parts omitted, and Fig. 3 is longitudinal vertical central sectional view of the valve mechanism regucooler.

y loting they circulation' of water forV the v ln the apparatusiillustrated, the sterilized .i

water, or other liquid to be cooled, is given a preliminary cooling by contact with a circulating cooling medium, such es water di-v rect from the street mains, before it is fed the ice bo-X and for this-purpose there is provided a cooler shown' fragmentary at 56, which includes an inner coil 57 adapted to be connected at its lower enduto a boiler, sterilizer or other suitable heating device for treating the liquid. The coil is incased `in a receptacle 59, which' is connected to some suitable source of cooling medium, `such as the street mains.' The cooler is also -tapped to receive an outlet pipe 62, which is provided with al valve 64. `The liow through this pipe is automatically controlled as will later be described The upper 'end of the coil 57 is connected to'a pipe 6 5 havingI a valve 67 forcontrollingthe flow of liquid therethrough. Theipipe is connected with the ice bon 76 for: supplying the same with the treated liquid `by automati' cally controlled means as will' later be described.

This ice 'box comprises an outer double wall y89 hai/ing a suitable non-conducting ller, and a cover 90 similarly constructed.

Within the box is an inner chamber 91 for l,

containingthe liquid, which converges toward the bottom to form a funnel which connects with one 'end of a coil 92. The other. end of the coil is connected -With the supply faucet 7 9 by means of which ther A cooled liquid is drawn as described.

The receptacle has anv overflowpipe 77, which dips in a trap 78, the liquid finally overovving from the trap into some suitable receptacle. Two ice receptacles 93-93 are placed between the chamber 91 and side Walls 89, and are of suitable-size to form -a space, 94 between them. The pipe 65 enters the ice tank and passesvthrough the space 94 to the 'chamber 91. -'lhe pipe is connected with a` valve 95 automatically controlled by the float`96. y

A spray pipe 9.7 extends from the valve 95 and throws the liquid `upon a vilter 98. The circulation pipe 62 is controlled by the rise and fall of the liquidin the chamber 91,

The pipe 62 is connected with a pipe'99, which extends through the space 94 into the chamber 91. This-pipe has aninner sic ' pipe 100 passing through it and is in communication with it at its inner end where a valve seat 101 is formed. This is adapted to engage with a valve 102. vA valve stem 103 connected to the yvalve 102 extends through the pipe 99 and 100 and acts on the valve to move the same to and from its seat by means of the float 104, which operates in the usual way with the rise and fall of the water in the receptacle 91. The opposite end of the pipe 100 extends through the pipe 99 and is connected to a pipe 105, which conveys the circulation water therefrom to the sewer orother suitable drain.4

In operation, the liquid is treated by some suitable heating process and conveyed to the cooler 56, and from there through the pipe 65 to the ice box 76, but is held in check by the ioat controlled valve 95, until the liquid in the chamber 91 of the ice box is vdrawn oil'. This lowers the surface of the water in the tank, thereby lowering the float 96. The valve 95 is thereby opened and the'liquid permitted to flow through the orifices in the pipe 97 until the float 96 rises sufficiently with the rising of the water to again close the valve 95.

The circulating water for the cooler 56 passes therefrom through the plpe 62 to the pipe 99 where it is checked by the valve 102 when the waterI in the chamber 91 is suiiiciently high t'o close the valve. When the water is' drawn from the chamber 91,

i the float 104 drops and opens the valve.

The circulating water in pipe 99 then flows into the pipe 100 and from here it flows into the pipe 105 and empties into the sewer. The cooling Water for the cooler 56 therefore only flows when the liquid in the chamber 91' is being withdrawn through the faucet 79, at which time the valve 95 is automatically opened bythe dropping of the float l96 and a further supply of liquid is permitted to How through the coil 57 at the same time cooling water-is permitted to iiow about the coil as just described.

B means of a device of this character, the iquid is cooled with an economical use of ice for the hot or warm liquid is given a preliminary cooling as it passes through the water jacketed cooler, which quickly lowers the temperature substantially to that of the water from the streetmains.

Further the spraying action of the pipel 97 has the edect of opening the body of liquid thereby facilitating the absorption of the heat therefrom by the ice in the outer compartment. gradually reduced in cross-section by means of the funnel shaped bottom thus bringing smaller and smaller volumes of the liquid under the influence of the cold bottom portion of the ice box and the liquid is then directed into the small bored coils directly under the ice receptacles.

The body of the liquid is The automatically controlled valves limit the amount of liquid admitted to the ice box so that the ice is not used in maintaining a large mass of the liquid at abnormal temperatures and at the same time, the device l is always open to a fresh supply of liquid.

Further by means of the float control valve the circulating water for the cooler is conserved and iows only when a fresh supply of the liquid is being fed to the ice box.

While I have shown and described, and have pointed out in the annexed claims, certain novel features of my invention, it

will be understood that various omissions,

substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention.
